In a post on his blog, South Australian Liberal Senator Cory Bernardi expressed concern that the filters would inadvertently block legitimate content and be expanded to cover other controversial material opposed by the Government of the day, such as regular pornography.

"Already we have a filter on the internet for all parliament house computers. It blocks some political sites, alternative lifestyle sites and other sites that, while not to my personal taste, are hardly grounds for censorship," he wrote.

"Imagine if such censorship was extended to every computer in the country through mandatory ISP filtering. Who would be the ultimate arbiter of what is permissible content?"

Bernardi, who tried to censor Gordon Ramsay by calling for a Senate inquiry into swearing on television in March, is known for his conservative views. The pro-life Senator has questioned whether global warming is caused by human activities, has opposed therapeutic cloning of human embryos and protested against proposed laws prescribing equal treatment of same-sex relationships.

With any luck, the whole scheme will disintegrate sooner rather than later.

A while ago, German national railway company Deutsche Bahn expressed an interest in running trains through the Channel Tunnel, competing with Eurostar, come 2010, when EU "open access" rules allow train companies to run services all over the EU. Now they're talking about buying out the UK's share of Eurostar altogether:

Deutsche Bahn (DB), Germany’s state-owned railway, may also use Eurostar trains to operate a rival service through the Channel Tunnel, with competition resulting in cheaper tickets to Paris and Brussels. But the Government, which is preparing to sell the third of Eurostar that it controls, would lose the ability to influence the development of the rail link to the Continent.

Over the past 18 months, it has quietly bought several British train companies that carry a total of 30 million passengers a year. DB owns Chiltern, which runs between London Marylebone and Birmingham, and half of London Overground, which operates on the North London Line and will serve the extended East London Line from next year. It also runs two thirds of Britain’s goods trains through its purchase of EWS, the biggest British rail freight company.

DB hopes to persuade Geoff Hoon, the Transport Secretary, that it will operate a more efficient service through the Channel Tunnel by drawing on its experience in Germany of integrating trains with other modes of transport. German rail passengers can book an entire journey on just one web-site and with one ticket and can even arrange for an electrically assisted bicycle to be waiting for them at the station.

DB have also expressed an interest in buying more train companies in countries they expand to; given their efficiency, that could be a good thing.

McMurdie said such a tool could run on suspects' machines, identify illegal activity - such as credit card fraud or selling stolen goods online - and retrieve relevant evidence.

"For example, look at breathalysers - I am not a scientist, I could not do a chemical test on somebody when they are arrested for drink driving but I have a tool that tells me when to bring somebody in."

Of course, knowing New Labour, this will probably result in legislation mandating police-accessible data-logging devices in all PCs. And the legislation will make these devices not only accessible to the police, but also to the Inland Revenue, TV Licensing, the British Phonographic Industry and local council officials. And, knowing that laws (specifically British laws dealing with privacy and data security) are drafted in a parallel universe in which security is perfect, there will be no possibility whatsoever of these devices either being defeated by the potential paedoterrorists they are meant to monitor or else hijacked by other criminals and used to massively victimise the innocent.
